Side Channel Blowers
Tulsi Pumps & Systems delivers high-performance side channel blowers engineered for industrial vacuum, pressure, and pneumatic conveying applications. Built for continuous duty with minimal maintenance.
Key Features
Engineered for demanding industrial environments, our side channel blowers deliver reliable performance where it matters most.
Oil-Free Operation
The non-contact impeller design eliminates the need for lubrication in the compression chamber. This ensures 100% oil-free air delivery, preventing contamination in sensitive applications like food processing, pharmaceuticals, and electronics manufacturing.
Low Noise & Vibration
Precision-balanced rotors and integrated silencers keep operating noise below 70 dB(A). The rigid cast iron housing absorbs structural vibrations, making these blowers suitable for indoor installations near workspaces without requiring additional acoustic enclosures.
High Efficiency
Advanced impeller geometry maximizes airflow while minimizing power consumption across the entire performance curve. With efficiency ratings up to 70%, these blowers reduce operational energy costs in continuous-duty pneumatic conveying and wastewater treatment systems.

Single Stage Side Channel Blower
Our single-stage side channel blower is engineered for applications demanding compact footprint without sacrificing performance. The streamlined housing integrates the impeller and drive motor into one rigid assembly, reducing installation space by up to 30% compared to conventional multi-stage units.
Pulsation-free airflow is achieved through precision-machined side channels that maintain constant pressure differential across the entire operating curve. This eliminates the surge and flutter common in lobe-type blowers, making it ideal for pneumatic conveying, wastewater aeration, and vacuum hold-down systems where steady flow is critical.
Double Stage Side Channel Blower
When your process demands higher pressure differentials, our double-stage side channel blower delivers. By integrating two impellers on a common shaft within a single compact housing, we achieve up to twice the pressure rise of a single-stage unit without adding external pipework or complex inter-stage cooling.
The dual-impeller architecture compresses air in two sequential stages, each optimized for a specific pressure band. This staged compression reduces thermal load per impeller, extends bearing life, and maintains the pulsation-free output characteristic that makes side-channel technology superior for sensitive instrumentation and precision vacuum applications.
Typical applications include central vacuum systems, high-pressure pneumatic transport over long distances, and process air supply for combustion where consistent pressure under varying load is non-negotiable. Available in both horizontal and vertical mounting configurations to suit your plant layout.

kWOperating Speed
High-speed impeller rotation generates consistent pressure and vacuum performance with minimal pulsation and vibration.
RPMHow It Works
Side channel compression operates on a simple three-stage principle that multiplies airflow energy without complex moving parts — delivering oil-free, pulsation-free performance in a compact footprint.
Intake & Pre-Rotation
Ambient air enters the blower housing through the inlet port and is immediately drawn into the side channel by the rotating impeller. The impeller's forward-curved blades impart kinetic energy, creating a spiral flow pattern that pre-compresses the gas before it reaches the first compression stage.
Side Channel Compression
As the impeller rotates, gas is repeatedly pushed through the annular side channel and recirculated back into the blade passages. Each revolution adds velocity and pressure through centrifugal acceleration — the gas spirals between blades and channel dozens of times per second, building compression incrementally without mechanical contact or lubrication.
Discharge & Pulsation-Free Flow
Compressed gas exits through the discharge port at a steady, pulse-free rate thanks to the continuous side channel design. Unlike piston or lobe compressors that deliver intermittent bursts, the side channel blower produces smooth, constant pressure ideal for sensitive applications like wastewater aeration, vacuum lifting, and pneumatic conveying.
Client Testimonials
Trusted by industries across India, our side channel blowers deliver reliable performance day after day. Here's what our customers say about working with Tulsi Pumps & Systems.
We installed four side channel blowers from Tulsi Pumps for our wastewater aeration system six months ago. The oil-free operation and consistent pressure output have exceeded our expectations. Maintenance has been minimal, and the team's technical support during commissioning was outstanding.
Rajesh Kumar
Plant Manager, AquaTreat Solutions, Surat
We needed a compact yet powerful vacuum solution for our packaging line. Tulsi's single-stage side channel blower fit perfectly into our space constraints while delivering the suction performance we required. Delivery was on time, and the pricing was competitive compared to imported alternatives.
Amit Patel
Production Head, PackRight Industries, Ahmedabad
After trying three different suppliers, Tulsi Pumps & Systems is the only one that consistently delivers blowers that match our specifications. Their side channel units run quieter than any we've used before, and the after-sales service response time is remarkably fast — usually within 24 hours.
Sanjay Mehta
Director, Mehta Engineering Works, Vadodara
Our textile processing unit relies on continuous airflow for drying and material handling. The side channel blower we purchased from Tulsi has been running 16 hours a day for over a year without a single breakdown. Genuine Make in India quality that rivals European brands at half the cost.
